Stanislav Fomichev e1cebd841b selftests/bpf: Fix a couple of broken test_btf cases
Commit 51c39bb1d5 ("bpf: Introduce function-by-function verification")
introduced function linkage flag and changed the error message from
"vlen != 0" to "Invalid func linkage" and broke some fake BPF programs.

Adjust the test accordingly.

AFACT, the programs don't really need any arguments and only look
at BTF for maps, so let's drop the args altogether.

Before:
